MAth160 CC Michael Jordan Message Discussion

In your first post to the discussion respond to each of the following numbered items.Watch Nike’s Michael Jordan Failure Commercial (30 sec) and then respond to the question. In this video, what is the main point of Michael Jordan’s message? You should be able to state his main point in one short sentence!Now watch Nike’s Michael Jordan Maybe It’s My Fault Commercial (1 min 2 sec) and then respond to the question. In this video, what is the main point of Michael Jordan’s message, and how is it related to the main point in his Failure video? You should be able to state his main point in one short sentence as well!What is the main point of the Annie Murphy’s blog post: When and How to Let Learner’s Struggle? You should be able to state her main point in one short sentence!From the reading, what are the three conditions that promote beneficial struggle? How are the messages in the article and the Michael Jordan videos related?Do any of your instructors use the three conditions that promote beneficial struggle? If so, explain how and give examples. If not, use this space to write a quick note to a generic instructor explaining the value of productive failure and how to set up the three conditions that promote beneficial struggle in the classroom learning environment.If you're comfortable sharing with your group, give an example in your own life where failure has been productive and actually contributed to your success (your instructor will read your response to this question as well). If you're not comfortable sharing a personal example, share how you plan to address setbacks in this class so that they contribute to your success.

PSY 520 Grand Canyon University Anxiety Descriptive Statistics Project

Topic 1 – Descriptive Statistics Project Directions: Use the following information to complete the questions below. While APA format is not required for the body of this assignment, solid academic writing is expected, and documentation of sources should be presented using APA formatting guidelines, which can be found in the APA Style Guide, located in the Student Success Center. A researcher was interested in the anxiety present in students just prior to the midterm exam. The researcher used an anxiety self-quiz to gauge the student’s anxiety. The score for 30 students are given here. 69 99 91 66 70 98 70 53 40 58 61 66 94 77 70 56 88 85 86 40 84 86 54 48 86 43 78 53 79 89 Construct a frequency table with class, frequency, relative percent, and cumulative percent that has 6 classes to describe the distribution of the data in SPSS. Use the frequency table to construct a histogram in SPSS. Use SPSS to calculate the numerical descriptive statistics mean, median, standard deviation, and variance of the anxiety scores.

PUBH 8500 Walden University Statistics Kaplan Meier Curve Discussion

Assignment: Kaplan-Meier CurveThe Kaplan-Meier curve is a way to evaluate longitudinal data and estimate conditional survival rates through the illustration of a series of conditional probabilities.For this Assignment, you use the Kaplan-Meier method to evaluate time-to-event data collected through a longitudinal study described in the Week 8 Dataset (SPSS document). You also create a survival curve and estimate survival distributions.The AssignmentUsing Week 8 Dataset (SPSS document) from the Learning Resources area, answer the following:Data (20 Points)Create a variable for Time-to-event by subtracting the start time (variable = start) from the stop time (variable = stop). Label the new variable “Time”. (10 Points)Produce the appropriate descriptive statistics, numerical and graphical, for the following variables: (10 Points)EventIntervalTxNumSizeTimeKaplan-Meier Survival Analysis (Without factor or Strata) (30 Points)Run a Kaplan-Meier analysis in SPSS, using Time as the Time variable and Event as the Status variable (Be sure to define the event). Do not add a factor or strata at this time.Produce a Survival Table (you do not need to submit this) (10 Points)Produce a plot of the survival function (10 Points)What is the mean survival time (include confidence intervals)? What is the median survival time (include confidence intervals)? Why do you think they are so different from each other? (10 Points)Kaplan-Meier Survival Analysis (With Factor) (30 Points)Run a Kaplan-Meier analysis in SPSS, using Time as the Time variable and Event as the Status variable (Be sure to define the event). Add Tx as the factor.Test the difference between Tx groups (Compare Factor) using Log-Rank, Breslow, and Tarone-Ware (10 Points)Produce a plot of the survival function (10 Points)Describe what the Overall Comparisons mean in terms of treatment groups and survival times. (10 Points)Kaplan-Meier Survival Analysis (With Strata) (20 Points)Run a Kaplan-Meier analysis in SPSS, using Time as the Time variable and Event as the Status variable (Be sure to define the event). Add Interval as the Strata variable.Produce a plot of the survival function for each strata. (10 Points)Why would you want to produce Kaplan-Meier Survival Curves after stratifying for a variable? (10 Points)
